I was honestly skeptical of this at first, I'm a left leaning and progressive guy, but it's been on my mind forever. But I've seen it first hand, having several non binary and LGBT+ friends. My reasoning is that when i was younger and went to school, meeting a lot of people who are still my friends today who are homosexual/non-binary, they all have some sort of mental illness or trauma. Bad relationship with their parents, anxiety, depression, all of it, they all have something going on. When my mom moved me out of a poorer area to a suburb and I had more friends in financially stable homes, I knew almost no homosexual people and it was a lot less prevalent. Both are in California by the way. But in every single case of a nonbinary and LGBT+ person or friend I knew, all of them had some sort of childhood trauma, or mental illness. I know correlation does not imply causation, but this seems very obvious. I had never really thought about it until last year, it was my first year of college and when quarantine started, many people were posting and being a lot more open about their sexuality, and also being a little too open about things they have been through. I'm not trying to be a bigot here, but it seems way too obvious.
